Without aid of stencils or brushes London-based artist David Walker creates elaborately explosive portraits using directly applied spray paint. Even as the colors drip and mix on large outdoor walls it’s hard to imagine the level of control and detail the artist must possess to create the shadows, lines, and textures that create each piece. The top and bottom pieces in this post are recent works seen in London and Paris, and you can see much more on his Facebook page and in his shop where he has nearly a dozen portraits available as high quality prints.
